Renewed December 24, 1938 1ol claims. (cl. 22o-14) lThis inventionrelates to 'containers for foodA andthe like, and particularly pertainsto a package.

When dispensing various products, such for 5 example as food products,and particularly butter, cheese, ice cream and the like, it is desirableto provide a package within which the product l may be thoroughlywrapped to preserve its davor and to prevent it from contamination anddeterioration before it is consumed.l Various cartons have been devisedwithin which such products may be placed, but these cartons arerelatively expensive .and consume considerable bulk before they arefilled. It is the principal object 15 of the present invention toprovide wrapping elements adapted to be cooperatively assembled to forma package within which a product may lbe placed and sealed, the saidelements being normally in the form of fiat sheets of material @designedto be folded to receive a product, and

having parts interlocking in a manner to malntain a sealed packageWithout the necessity of 30 seal the product.`

The invention is illustrated by way of example and in the accompanyingdrawings in which:

The four4 elements previouslymentioned are all ofthe elements refragmentary view` in l0 indicates alining wrapper within which a..

,quired to form the package with 'which the y not'necessary' for thehuman hand to touch .the

product within the .finally sealed package.

Referring particularly to Fig. 1 of the drawings in which the liningwrapper I0 is disclosed,

. gies to the score marks it will be seen that a central field I4 isformed and is defined by scoring marks I5 which here are shown asdefining an octagonalneld. The field 'I4 is bounded by a marginalportion of uniform width whereby a larger octagonal shaped sheet isdefined. This-marginal portion .comprises a plurality of rectangularnelds I5 bounded on their innersides by the scoring marks I5 and ontheir outer sides by an edge I1. The ends of these rectangular fieldsare dened by parallel.

score marks I I which are disposed at right an- I5. The outer edges I1continue beyond the score marks I3 to a point of Intersection and amedian score mark I9 extends from this point to the point of convergenceof contiguous score marks I8. Alternate fields I6 are formed with tangswhich extend beyond score marks I1', which marks are a continuation ofthe marginal edges II of these fields. 'I'he tangs are of a widthagreeing with the'distance between score marks I8 and of a suitablelength for a purpose to be hereinafter set forth.

A The corners of -the tangs have been cut away at an inclination tofacilitate in a sealing operation to be hereinafter described.

Referring more particularly to Fig. 4 of the drawings, it will be seenthat the cover wrapper II is shown in detail. The cover wrapper II is inthe form of a flat sheet of material and is square in shape. This sheetof material is cut and scored to form a folding structure. An octagonalcenter field 2I is disclosed bounded on its sides by score marks 22. Thesize of the octagonal field 2I is slightly greater than the size of theoctagonal field I5 of the lining wrapper, since the lining wrapper fits-within the folded cover wrapper as will Vbe hereinafter described.Corner tangs 23 are formed as a part lof the cover Wrapper and occur atthe corners of the square blank of the cover wrapper. These tangs aredefined by marginal edges 24 which are the corners of the blank. 'Iheedges 24 terminate in shoulders 25 disposed at right anglesthereto. tendinwardly toward leach other Auntil they intersect the edgeswhichemanatefromand are at right angles to score marks :22. Thescoremarks 22 as previously stated deflneathe config uration of theoctagonal field 2i. The edgesl are parallel to each other and are aparta distance equaLto the length of a score mark 22.` Formed parallel tothe score marks 22 and extending from the inner` end of one shoulder 25to a complementary shoulder 25 is a scoremark 2l provided for a purposeto be hereinafter set forth.

occurringbebween the corner tangs 23 are side folds `2l which have anouter edge A23.

being continuations of edges 24 of the tangs 23. The length of the edges23 represent Vthefdistance between shoulders 25 on adjacent cornerlfilings A23. The folds 2l are defined along their inner Vedges by"previously mentioned score marks v22.

Two score marks 3l extend from the ends of the score mark 22 tothe outeredge 2! and divide the folds n inw three sections rectangular centersection 3i and two end flaps 32. The end flaps areofa tionsupplementaltothatof ashoaxlder 25 and aside 25 ofamrner tang 23. Cut into eachoftherectangularsections 3i isa slit 33 whichis paralleltotheoutermarginaledge 2l andisalsospacedreiatively close thereto. This slitextends fora maior length of thedistance between the scoremarks- 3l andadjacent to its ends'are small right angle slits 24.1 These membersreceive tang: of a part hereinafter to be The shoulders 25 ex' arcaocoReferring to 213.49 or the drawings the top sheet I2 is disclosed. Thisis a square ilat sheet having vdiagonal scoring marks across its cornerportions so that the marginal edges and the scoring marks willdeflne anoctagonal s' tions being scored transversely at 3l so that the 15 scoremarks 38 and the marginal portions of the edges of the blank will'forman octagonal field 39 substantially that of the octagonal field 2I oithe cover wrapper.' Corner tan'gs 40 will thus be formed. These tangshave marginal edges 4I zo disposed at right angles at the corners of theblanks and locking shouldersv 42. The overall distance from the junctureof the marginal edges 4I and the locking shoulders 42 is slightly lessthan the length of the slits 33 in the cover wrap- 25 per I I. The widthbetween the inner ends of the shoulders 42 on the tang substantiallyagrees with the distance between the short slits 34 on the cover wrapperI I,..so that these parts will be locked together.

In forming a package with the lining Wrapper I0. the top lining sheetI2, the cover wrapper II, and the cover top sheet I3, the followingrprocedure is preferable. A mold 45 is provided having a cavity sameconfiguration as the center fleld I4 ofthe lining wrapper, thedimensions, however, being slightly greater than. the dimensions of thatfield. A plunger 41 is provided to operate in conjunction with themold45. The lining wrapper Il is n then suitably positioned over the cayityinthe mold, as shown in Fig. 2, after which the plunger 46 therein. Thiscavity is of the 35 formed {containenand the marginal portinnsvii a,

will fold' upf along the sides to provide the sides of an octagonal-wallstructure. The tongs 2l will extend upwardly'v around. the edges of thecontainer thus formed and the portions oi the blank occurring betweenthe adjacent-rectangular n sections Ii will be folded upon themselves,as indicated at '43 in 3l and 131.

` It will thus be seen that the package here disclosedV is formed bytheause of inexpensive .flat sheets of suitable materiallwhich do notrequire the use of expensive machinery .or preforming dies in making acontainer, but make it possible for a package to be made and assembledprogressively as the parts are folded andas the food product isdeposited therein and sealed.-

It will also be evident that due to the shape of the package formed itmay be placed in a storage space, such as a mechanical refrigerator,either fiat or edgewise, since it occupies asmall space and can beconveniently packed in with other containers.

While- I have shown the'preferred form of my invention, as now known tome, it -will be understood that various changes might be made in thecombination, construction, and arrangement of parts by those skilledinthe art, without departing from the spirit of the invention asclaimed.

-Havingy thus described my invention, what I claim and desire to securebyLetters Patent is:
